Greatest Common Divisior

We found the divisors of 210, 211, 561 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 210, 211, 561 is 1.

Therefore, GCD of numbers 210, 211, 561 is 1

Given Input Data is 210, 211, 561

Make a list of Prime Factors of all the given numbers initially

Prime Factorization of 210 is 2 x 3 x 5 x 7

Prime Factorization of 211 is 211

Prime Factorization of 561 is 3 x 11 x 17

The above numbers do not have any common prime factor. So GCD is 1

Step1:

Let's calculate the GCD of first two numbers

The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)

LCM(210, 211) = 44310

GCD(210, 211) = ( 210 x 211 ) / 44310

GCD(210, 211) = 44310 / 44310

GCD(210, 211) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 561

The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)

LCM(1, 561) = 561

GCD(1, 561) = ( 1 x 561 ) / 561

GCD(1, 561) = 561 / 561

GCD(1, 561) = 1

GCD of 210, 211, 561 is 1
